Design And Implementation Of 2050 Dynamic Display System For Rough Roll Process

The technology of tri-dimensional animation simulation is an important way of simulating the real scene. It is widely used in many fields. The real-time simulation communication and tri-dimensional animation making technology are important research directions.2050 rough rolling dynamic simulation system is used for simulating the 2050 rough rolling mill, MMI(man-machine interface) subsystem displays the current simulation state of the whole simulation system and the manufacture process by tri-dimensional animation, and communicates with other systems to receive animation data. The operators and others can monitor the real scene through MMI computer. The analytical strategy of the research focuses on the above questions based on MMI subsystem, and after investigation, the main results are got as follows.(l)In the process of system design, the thesis introduces some principles should be abided by in software design. Abided by these principles, four modules are devided in the design of the system. They are foundation object layer, graphics object layer, scene node layer, painting and alternation layer. Specifical data struction and arithmetic are also realized in these four layers. All the programs are coded in C++ programming language. Because the models of the system must be tri-dimension, OpenGL (Open Graphic Library) is imported in this process, which is a tri-dimension graphic development API (Application Programming Interface). The operation system selected for development is Windows 2000, and the program platform is Visual C++6.0.(2)OpenGL is standard for high performance 2D/3D graphics on devices, but programming with OpenGL only is complex and difficult. A way of combining 3D Max with OpenGL is proposed. Experimental results show that obj file exported from 3D Max can be identified and used by OpenGL, and many complex graphics can be drawn in 3D Max , a lot of programming time is saved.(3)Particle system can simulate many natural phenomenon, such as flame, fountain, explode, shoal, gas, stars etc. The principles of them are similar. Particle system is made up of limited particle. The limited particle is used to simulate the effect...
